i have tuple of numbers, , want choose random number tuple in addition number. example:

my_tuple = (1,2,3)

and have number 4. want choose random number numbers 1,2,3,4 (without changing tuple of course).

i tried:

my_tp = (1, 2, 3) = random.choice(list(my_tp).append(4)) print(a)

i'm new python. tried converting tuple list, , performing random function. code above didn't work. got error

object of type 'nonetype' has no len()

would love help.

`list.append` returns `none`

once converting list have done, appending modify list return none source of error.

to round can either convert tuple list append 4 it, use random.choice, or in 1 step, can concatenate list of [4] + operand.

this approach simpler:

import random  my_tuple = (1,2,3) random.choice(list(my_tuple) + [4])

hope helps , clears things up! :)

update:

if want randomly select tuple without last item, slice list normal syntax:

random.choice(list(my_tuple)[:-1])
